A well-defined poly(N-isopropyl acrylamide) 1 incorporating at one termini a cyclobis(paraquat-p-phenylene) (CBPQT(4+)) recognition unit is prepared via a RAFT polymerization followed by a copper-catalyzed azide-alkyne cycloaddition (CuAAC). (1)H NMR (1D, DOSY), UV-vis and ITC experiments reveal that polymer 1 is able of forming effective host-guest complexes with tetrathiafulvalene (TTF) end-functionalized polymers in water, thereby leading to the formation of non-covalently-linked double-hydrophilic block copolymers. The effect of the temperature on both the LCST phase transition of 1 and its complexes and on CBPQT(4+)/TTF host-guest interactions is investigated.
一种明确的聚（N-异丙基丙烯酰胺）1 在一端结合了一个环双（paraquat-p-亚苯基）（CBPQT（4+））识别单元，是通过 RAFT 聚合，然后通过铜催化的叠氮-炔环加成（CuAAC）制备的。（1）H NMR（1D，DOSY）、UV-vis 和 ITC 实验表明，聚合物 1 能够在水中与四硫富瓦烯（TTF）端功能化聚合物形成有效的主客体配合物，从而形成非共价键连接的双亲性嵌段共聚物。温度对 1 及其配合物的 LCST 相变以及 CBPQT（4+）/TTF 主客体相互作用的影响进行了研究。
